for-n fe tn sanding or polishing operations.

For sanding operations it is essential that the abrasive sheet be.heldfirmly. against slipping or wrinkling. It is also essential, that,the user-be able to hold and manipulate the, abrasive firmly. andcomfortably. I

It is one ofthe objects'ofthe present inven tion toprovide a sandingdevice which will hold; an abrasivezsheet. firmly: and which is easy andcomtenienttoihandlei. v

A further object is to provide an extremely simple and efiicientfastening means to secure the fastening plate to the blade.

The above and other objects and advantages of the invention will be morereadily apparent when read in connection with the accompanying drawings,inwhich- Figure l is a perspective view of a sanding device embodyingthe invention;

Figure 2 is a view similar to Figure 1 showing the parts disassembled;

Figure 3 is a longitudinal central section through the device of Figure1;

Figure 4 is a transverse section on the line 4-4 of Figure 3; and

Figure 5 is a view similar to Figure 4 showing an alternativeconstruction.

The sanding device of the present invention consists essentially of aflat, relatively thin blade indicated generally at l and a handle llrigidly secured to the blade and extending at an obtuse angle therefromat one end. The blade is preferably made of sheetmetal and may beattached to a separate handle I I, as illustrated, or may have thehandle formed integrally therewith, if desired. The blade in the formshown in Figures 1 to 4 includes a flat central portion and edgeportions I2 which are turned up slightly at an obtuse angle to avoidsharp corners on the working surface of the blade. In its central partthe blade carries an upstanding ear I3 which may be welded or riveted tothe metal blade and which is formed with an opening l4 therethrough.

The blade is adapted to receive an abrasive sheet l5 such as sandpaper,emery paper, or the like and which is rectangular and of slightly reaterh baa h e ies-1L lteblb he We 5 im l red. a wh te ail he al lees hfi as"'1 blade as in cat Q: a 1 esteadovertheus etd r b a eases J1. 9 theblade to the flat top surface thereof.

'Taholld; fast nin plate, it is provided with a U-shapedopening 18 leaving a tongue l9 extending longitudinally of the plate andof a size to be received in the opening I4 of the ear l3.

To use the device an abrasive sheet maybe I) folded around the blade, asillustrated, and the fastening plate l6 may be placed over the blade andthe sheet and slid longitudinally to move the finger [9 into the openingI l. This will securely hold the fastening plate over the blade,pressing the edges of the blade against the abrasive sheet to hold ittightly against shifting. The blade itself and the finger l9 willprovide sufiicient resiiience to insure tight gripping of the abrasivesheet. With the sheet secured in place, the user may grip the handle Hand may manipulate the device much in the manner of a file. The upwardlyturned edge 12 will insure against sharp corners on the working surfacewhich might bite into the work so that the device can be used easily andeifectively. Worn abrasive sheets can be replaced very easily andquickly and will be securely held against the blade when in use.

In the modification illustrated in Figure 5, the blade 10' is rolledupward at its edges, as indicated at 12' to provide rounded bead likeedges. The fastening plate [6' is narrower than the space between therolled edges I2 so that it will grip the abrasive sheet IS in the mannerillustrated. Otherwise this construction is the sameas that of Figures 1to 4 and function in exactly the same manner.

While two embodiments of the invention have been shown and described indetail herein,; it will be understood that they are illustrative onlyand. are not to be taken as a definition of the scopeof the invention,reference being had for this purpose to the appended claims.

What is claimed is:

1. A sanding device comprising a handle and a blade rigidly connectedend to end and lying at an obtuse angle to each other, the blade beingadapted to receive an abrasive sheet overlying the blade bottom with itsedge portions folded over the edges ofthe blade and extending partiallyover thejtopof the blade, at fastening ear extending upward from the topof the blade, a fastening plate to overlie the top of the blade and gripthe folded edges of the abrasive sheet, and an integral finger on theplate to engage the fastening ear upon sliding the plate relative to theblade to secure the plate to the blade;

2. A sanding device comprising a handle and a blade rigidly connectedend to end and lying at an obtuse angle to each other, the blade beingadapted to receive an abrasive sheet overlying the blade bottom with itsedge portions folded over the edges of the blade and extending partiallyover the top of the blade, a fastening ear extending upward from the topof the blade and having an opening therein, a fastening plate to overliethe top of the blade and grip the folded edges of the abrasive sheet,the plate having an opening therein through which the ear may project,and anintegral tongue on the plate to fit into the opening in 'the earto secure the plate to the blade.

- 3. A sanding device comprising a handle and a blade rigidly connectedend to end and lying at an obtuse angle toeach other, the blade beingadapted to receive an abrasive sheet overlying the blade bottom with itsedge portions folded over the edges of the bladeand extending partiallyover the top of the blade, a fastening ear extending upward from the topof the blade and having an opening therein, a fastening plate to overliethe top of the blade and grip the folded edges of the abrasive sheet,the plate having a U-shaped opening therein to receive the ear and todefine an integral tongue adapted to fit into the opening in the ear tosecure the plate to the blade.

A sanding device comprising a handle and a relatively thin fiat bladelying at an obtuse angle to the handle, the handle being bent upward atits edges and adapted to receive an abrasive sheet overlying its bottomwith its edge portions folded over the upwardly bent edges of the bladeand extending partially over the top of the blade, a fastening plate tofit over the top of the blade between the upwardly bent edges to gripthe folded edges of the abrasive sheet, an upwardly extending ear on theblade having an opening therein, the plate having an opening therein toreceive the ear, and an integral tongue on the plate to fit into theopening in the ear to secure the plate to the blade.
